The Model 900C/RS232 is a Microprocessor based
Controller/Timer. It monitors temperature utilizing a Type J thermocouple sensor
and controls bath temperature with a standard three mode (PID) control scheme,
with anti-reset windup. Numerous status and alarm functions are incorporated to
monitor various system parameters. A Timer with count-thru and pre-warn is
integrated into the system.
